Borosilicate glass has high thermal resistance and chemical durability. This is achieved through the addition of boron trioxide in the manufacturing process. Vessels made from borosilicate glass are suitable for laboratory and kitchen use.

Soda lime glass is the most common type of glass (approx 90% of all manufactured glass is soda lime). It is made from silica sand, sodium oxide (soda) and calcium oxide (lime). It has excellent optical clarity and is the economic choice. However, unlike borosilicate glass, it has low resistance and may crack if exposed to sudden temperature changes.

• Type 1 glass is Borosilicate glass; this type of glass has high thermal shock resistance, so it can withstand high temperatures, it has high chemical resistance and is autoclave safe. This is why type 1 Borosilicate glass is the standard glass for laboratory, scientific and oven use.
• Type 2 glass is treated soda-lime glass. It is a specialist glass designed for use in the pharmaceutical and medical industries for liquid medications.
• Type 3 glass is standard soda-lime silica glass. It is the most common type of glass and is the glass used for jam jars, beverage bottles and .

Soda glass containers are suitable for storing powders and liquids.

Borosilicate glass is designed for laboratory use. It has high thermal and chemical resistance, so it is suitable for storing chemicals and for use in heated lab tests and experiments.

Yes, all our glass bottles, beakers and vials are safe for food use.

It depends; our reagent bottles, powder bottles, and glass vials all come complete with screw-top closures. Closures must be ordered separately for our Winchester glass bottles. Matching closures can be easily ordered from the product page using the "quick add" function.

Coloured glass containers, like our amber glass bottles and jars, block UV light, they are used for light-sensitive powders, pastes and liquids.

Amber glass containers offer excellent UV protection

Sample bottles are available in a wide range of sizes. The smallest size is 1.75ml. 7ml and 28ml are also available to purchase online, with other sizes available on request.

Winchester bottles are known as Boston rounds in the US. They have a flat base, a wide cylindrical body and a rounded shoulder that tapers to a narrow neck. The bottle is designed to be stable and easy to pour. They are often made from thick amber glass to protect the contents from light degradation. Winchester bottles are commonly used for liquids, oils, chemicals, solvents and pharmaceuticals.
